    Add cleanwait timeout cleanup process

    Previously, if a node in a cleaning state timed out, the timeout
    process would not purge certain items from the node's configuration
    which resulted in a short circuiting of the logic cleaning being
    retried. This was a result of the node clean_step configuration
    not being purged upon a timeout occuring.

    This change adds a wrapper method around the cleaning failure
    error handler to allow the _fail_if_in_state method to call
    the error handler, since error handler syntax is not uniform
    and the _fail_if_in_state cannot pass arguments.

    It also changes the cleaning error handler to permit the error
    handler to delete the node clean_step, and cleaning related
    driver_internal_info configuration from a node in the event
    the node in in CLEANFAIL state.
